This instrutable will teach you how to create an automatic marshmallow gun out of 1/2 inch pvc pipe. This is my first instructable so feel free to give me suggestions of what i could do better.

Step 1: Materials

To make this gun you will need:
2 1/2 inch pvc caps
2 1/2 inch pvc elbows
2 1/2 inch pvc tees
4 5-inch sections of 1/2 inch pvc pipe
1 11 inch pvc pipe (barrel)
1 8 inch pvc pipe (hopper)
1 9 inch pvc pipe (mouth piece)
cotton balls

Optional:
Electrical tape (for looks)

Step 2: Asslembling Mouthpiece

To make the mouthpiece you will need to connect the 9 inch pipe to an elbow connect that to a 5 inch section and connect that to a tee.

Step 3: Assembling Hopper

To make the hopper you will need to attach a cap to the 8 inch pipe, then on the other end attach a tee and to that attact a five inch section.

Step 4: Asslembling Handle

To make the handle you will need to attach 2 5ive inch pieces to an elbow and put a cap on one of them. The piece without the cap needs to be suffed with cotton balls. The other piece shall remain hollow so you can fill it with marshmellows (can not hold very many but why not?)

Step 5: Put It All Together

In this step we will put all pieces together and attach barrel.

Step 6: If There Was Any Confusion

Just in case you didnt understand anything here is a more detailed picture if everything.

Step 7: Usage

In order to use this gun you first need to load the hopper (8 inch pipe) with mini malshmallows (mine held 15). Then you need to reattach to gun, aim in a safe direction, and blow continuisly through mouthpiece. If all went well all 15 marshmellows should have left the barrel. Mine shoots a good 20 yards.

Step 8: Modification

There are many improvements that can be done to this gun. I wrapped electric tape around mine to give it a better apperance. You could also put another tee, behind the hopper, facing down and attach another handle. You could ajust the lenght of the pipes for a bigger or smaller gun. There are an infinate amount of possibilites.
